Robot Evaluation Model

For the product to be applicable in everyday life, quality assessment must be performed in advance.

For robots without set methods of quantitative quality evaluation, a trustworthy comprehensive evaluation model is under development by cooperating with various expert research teams.

Case 1: Development of an evaluation model for industrial wearable robots through cooperation with research teams specializing in the field of ergonomics

Research Background

While we have developed an industrial wearable robot as a solution to musculoskeletal disorders in industrial environments, there is a clear lack of evaluation methods for the chair-type wearable robot cex and arm-supporting wearable robot vex. 

Research Details

1. An evaluation model for the quantitative and qualitative reduction of work load through a 5-step process from the selection of evaluation index to the final model proposal and extraction of improvement measures 

2. Quantitatively, the final evaluation model measures changes in a worker's biomechanical indicators (muscle activity and waist load) and physiological indicators (heart rate and skin temperature) during work

3. Qualitatively, by measuring the change in workability index (work time and error rate) and subjective index (discomfort level of entire body and each body part), the work load can be numerically calculated

4. 4. Based on the completed comprehensive evaluation model, an evaluation is performed to verify the effect of VEX on workload reduction

- An evaluation is conducted on the five major working postures that are most commonly used in real-life industrial sites

- By analyzing the evaluation data, the workload reduction of workers wearing CEX/VEX can be verified in numerical value. Improvements regarding future models can be proposed by identifying the weaknesses of the current model

Effects of Research

The comprehensive evaluation model developed through this research leads the field of systematic research regarding the development and evaluation of domestic and international wearable industrial robots, significantly contributing to Robotics LAB’s position at the forefront of the industry.
